Investigation of Rotor Tip Vortex in Hover Based on IDDES Methods

Xibei Gongye Daxue Xuebao, 2019
A calculation and analysis program of high-precision numerical simulation for rotor blade tip vortex in hovering state was developed. The fifth order Roe-WENO scheme was carried out in order to reduce the numerical dissipation of the rotor wake region ...

Wind tunnel investigation of the aerodynamic characteristics of five forebody models at high angles of attack at Mach numbers from 0.25 to 2 [PDF]

Five forebody models of various shapes were tested in the Ames 6- by 6-Foot Wind Tunnel to determine the aerodynamic characteristics at Mach numbers from 0.25 to 2 at a Reynolds number of 800000.

Global MHD Simulations of Accretion Disks in Cataclysmic Variables (CVs): II The Relative Importance of MRI and Spiral Shocks

, 2017
We perform global three-dimensional MHD simulations of unstratified accretion disks in cataclysmic variables (CVs). By including mass inflow via an accretion stream, we are able to evolve the disk to a steady state. We investigate the relative importance

Cost‐effectiveness of a randomized controlled trial comparing low‐dose aspirin to placebo for the prevention of recurrent preterm birth

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 399-407, April 2025.
Abstract To assess the cost‐effectiveness of low‐dose aspirin compared to placebo for the prevention of recurrent preterm birth from a healthcare perspective. This was a cost‐effectiveness analysis alongside a multicenter, randomized, double‐blinded, placebo‐controlled trial.

Interstellar Sonic and Alfv\'enic Mach Numbers and the Tsallis Distribution

, 2011
In an effort to characterize the Mach numbers of ISM magnetohydrodynamic (MHD) turbulence, we study the probability distribution functions (PDFs) of patial increments of density, velocity, and magnetic field for fourteen ideal isothermal MHD simulations ...

Vocal Fold Scar Treatment via Controlled Dexamethasone Delivery With a Light‐Activatable Implant

The Laryngoscope, EarlyView.
A light‐activatable dexamethasone implant was employed for the treatment of vocal fold (VF) scarring in a rabbit model. The implant enables controlled, repeatable drug release via near‐infrared laser irradiation, improving biomechanics, vibratory function, and histological architecture at the injury site.

Analysis of Influencing Factors of Boundary Layer Transition During Ascent Phase of Hypersonic Vehicle

气体物理
The transition of the boundary layer is an important issue that must be considered in the design of hypersonic vehicles. During the ascent phase of the vehicle, both the Mach number and the flight altitude increase simultaneously and affect the location ...
